Comprehensive Questions (Frequently
Tested) with Verified Answers Graded A+
Approved - Answer: Acceptable to the authority having jurisdiction.
Connected - Answer: Bonded is defined as————- To establish electrical continuity and
conductivity
Bonding Conductor or Jumper - Answer: A reliable conductor to ensure the required electrical
conductivity between metal parts required to be electrically connected.
Main - Answer: The connection between the grounded circuit conductor and the equipment
grounding conductor at the service is accomplished by installing a(n),
Cabinet - Answer: An enclosure designed for either surface mounting or flush mounting
provided with a frame in which a door can be hung is called a,
Establishes a connection - Answer: A shoulderless pressure connector is a device that between
two or more conductors or between one or more conductors in a terminal by means of
mechanical pressure and without the use of solder,
Disconnecting means - Answer: A device, or group of devices, by which the conductors of a
circuit can be disconnected from their source of supply.
All of these - Answer: As used in the NEC, equipment includes
fittings, appliances, machinery.
, Exposed - Answer: As applied to wiring methods, " on or attached to the surface, or behind
access panels designed to allow access" is known as.
A fitting - Answer: An accessory such as a locknut, intended primarily to perform a mechanical
rather than an electrical function.
Ground - Answer: The word "Earth" best describes what NEC term?
Ground fault - Answer: An unintentional, electrically conductive connection between an
ungrounded conductor of an electrical circuit and the normally non-current-carrying
conductors, metallic enclosures, metallic raceways, metallic equipment, or earth.
Grounded - Answer: Connected (connecting) to ground or to a conductive body that extends
the ground connection is called,
Grounded conductor - Answer: A system or circuit conductor that is intentionally grounded.
Ground Fault Circuit Interrupter (GFCI) - Answer: A device intended for the protection of
personnel that functions to de-energize a circuit or portion thereof within an established period
of time when a current to ground exceeds the values established for a Class A device.
6mA - Answer: A class A GFCI protection device is designed to trip when the current to ground
is————-Or higher.
Electrical supply source - Answer: A ground-fault current path is an electrically conductive path
from the point of a ground fault through normally no current-carrying conductors, equipment,
or the earth to the?
Ground-Fault Protection of Equipment - Answer: A system intended to provide protection of
equipment from damaging line-to-ground fault currents by causing a disconnecting means to
